This blog post will go through new replication features in ClusterControl 1.4.0, including enhanced multi-master deployment, managing replication topology changes, automated failover and handling of replication errors.
In our previous post, we showed you how to shard your MongoDB databases and covered the theory behind it. But you are not done yet. How do you monitor the shards to make sure they are performing, and that data is distributed evenly between your shards? And how do you consistently backup your data across shards? This is our ninth post in the “Become a MongoDB DBA” blog series.
Database Cluster management tasks include restart/recovery of services that fail, topology changes, reconfiguration, rolling upgrades, backups and performing security procedures. Since the tasks usually involve multiple servers, these can be repetitive and error-prone. This blog looks at efficiency gains when using ClusterControl to manage a MySQL Galera cluster as compared to manual ways.

We have recently updated our tutorial on MySQL Load Balancing with HAProxy. Read about deployment and configuration, monitoring, ongoing maintenance, health check methods, read-write splitting, redundancy with VIP and Keepalived and more.
Of the different types of clustered MySQL environments, NDB Cluster is among the ones that involves more effort and resource to administer. And unless you are a command line freak, you would want to use a tool that gives you a full view of what is going on in your cluster. It is possible to install ClusterControl and monitor your existing MySQL Cluster (NDB). In this blog post, we are going to show you on how to add two existing MySQL Clusters (production and staging) into ClusterControl.
During the life cycle of Database installation it is common that new user accounts are created. It is a good practice to once in a while verify that the security is up to standards. That is, there should at least not be any accounts with global access rights, or accounts without password. Using ClusterControl, you can at any time perform a security audit.
Requires ClusterControl 1.2.11 or later. Applies to MySQL based clusters. From time to time it is necessary to tune and update your configuration. Here we will show you how you can change/update individual parameters using the ClusterControl UI. Navigate to Manage > Configurations.
Join us for this live webinar on Tuesday, October 27th, led by our colleague Art van Scheppingen, Senior Support Engineer at Severalnines. Art recently joined us from Spil Games in Amsterdam, where he was Head of Database Engineering. He’ll be discussing and demonstrating the new release of ClusterControl and will be available for questions on its new features.
We were delighted to announce that ClusterControl now supports MaxScale, the intelligent database gateway from the MariaDB team. In this blog, we will show you how to deploy and manage MaxScale from ClusterControl. We previously blogged about MaxScale, read it if you’d like a quick overview and introduction. We also published a quick benchmark of HAProxy vs MaxScale.
